VMS Help System Services, $DNSW (VAX Only)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    On VAX systems, is the client interface to the DIGITAL
    Distributed Name Service.

    The $DNSW service completes synchronously; that is, it returns to
    the caller after the operation completes.

    For asynchronous completion, use the $DNS service, which returns
    to the caller immediately after making a name service call. The
    return status to the client call indicates whether a request was
    successfully queued to the name service.

    In all other respects, $DNSW is identical to $DNS. Refer to
    the $DNS description for complete information about the $DNSW
    service.
